Abstract
A writing instrument with no moving parts comprising of a rigid primary barrel (2) abutting a deformable elastomeric finger grip element (6) both with a communicating longitudinal through bore (4) (20) devoid of any ink cartridge or refill. The through bore of the primary barrel (4) is formed to accept a common disposable stick pen or common pencil (16). The through bore (20) of the elastomeric finger grip element (6) is formed to be slightly narrower in diameter than the outside diameter of a disposable stick pen (16) or pencil and thus captures an inserted stick pen by way of friction. The elastomeric grip is the sole means for retaining a stick pen or pencil used as a refill within the writing instrument barrel. The primary barrel has formed to it an integral, parallel, secondary barrel (12) that retains a ball chain (14) or cable to be secured to an object or a work station to discourage theft.
Description
- This patent claims the benefit of provisional patent application Ser. No. 62/176,122 filed Feb. 10, 2015 by the present inventor.
- Not applicable
- Not Applicable
- Field of Invention
- This invention relates to an improved security pen, also known as a counter pen, specifically the type that is tethered by chain or cable to a service counter to prevent removal of the pen from the counter or work station.
- Prior Art
- Businesses, institutions and governments world-wide use counter pens or security pens at their service counters to prevent the accidental or purposeful removal of pens that are provided to customers for their signature or to fill out a form.
- The current selection of security pens available is basic, unattractive, not brandable and of varying quality. Most models available today are refillable with new ink refills but some are not, they must be discarded. There is one common problem with all security pens currently available. The one common liability that virtually all prior art in the security pen category possess is the actual pen component. The refilling process for security pens with fresh refills is a burdensome task. It is the pain point. One must disassemble the pen and determine which specific refill their model of security pen requires. There are at least five standard refills available for the security pen product category. New refills must be ordered from a stationary supplier on-line or by telephone. A waiting period for product to be delivered exists. Once new refills are delivered the dysfunctional pen must be disassembled, refilled and reassembled. An inventory of refills ordered must be stored in a location that must be remembered at some future date when the refilling process must be repeated. This entire process is a frustration for those assigned with the task of maintaining the security pens in their operation.
- Businesses, institutions and governments worldwide use security pens at service counters. Prior art has not offered a substantive innovative solution to the common frustration of the refilling process. The frustrating task of refilling a security pen with a fresh refill is universal.
- Prior art appears to be concerned with other aspects of security pen issues such as the tethering system, holders and caddies. U.S. Pat. No. 6,854,681 to Kish, February 2005 discloses a retractable pen/stylus holder. U.S. Pat. No. 5,947,623 to Smith, September 1999 discloses a recoiling, replaceable chain marking device. U.S. Pat. No. 7,059,797 to Sellars, June 2006 discloses a writing instrument with simultaneous features for promotion and discouraging theft. U.S. Pat. No. 6,167,596 to Berman, January 2001 informs us of a pen and holder requiring no tools for replacement of a used up pen. U.S. Pat. No. 8,172,474 to Dickover et al, May 2012 discloses a hollow bodied writing instrument titled ‘Pen tether compressive disconnect.’ Although security pens possess numerous liabilities the main issue is the ongoing and frustrating challenge to replace old refills with fresh refills.

FIG. 2A —Description of Primary and Secondary Barrels - A
primary barrel 2 is formed to create a rigid, generally cylindrical barrel with a throughbore 4 along the longitudinal axis. Theprimary barrel 2 could be injection molded of a thermoplastic material which is the preferred embodiment. The throughbore 4 would be sized to accept anydisposable stick pen 16 presently in use. The through bore of theprimary barrel 4 would be formed to have a greater inside diameter than the outside diameter of any stick pen available. Theprimary barrel 2 could also be formed of wood, bamboo or synthetic material using various methods such as turning on a lathe which would result in a cylindrical barrel. - The
secondary barrel 12, adjacent toprimary barrel 2 would be integrally formed to the primary barrel. The internal diameter of the throughbore 18 of thesecondary barrel 12 would accept a ball chain, the preferred embodiment, or a narrow cable. The internal walls of throughbore 18 would be tapered from top to bottom, wider at the top. Aball chain 14 affixed with apendant 24 at its distal end would be permitted to enter the bore at the top end of the secondary barrel but the pendant would be prevented from exiting at the lower end due to the reduced internal diameter of the throughbore 18 at the lower end. -
FIG. 2A —Description of Primary Barrel Bushing -
FIG. 2A shows the primarilybarrel 2 would be reduced in diameter at its lower end to form anintegral bushing 10.Bushing 10 would be the connection point between theprimary barrel 2 and theelastomeric finger grip 6. The outside diameter of the Bushing would be approximately that of the inside diameter of thefinger grip 6.Bushing 10 would be inserted into the throughbore 20 offinger grip 6 and permanently affixed with a suitable adhesive. There are various possibilities with regard to affixing the primary barrel to the finger grip but the one presented is the preferred embodiment. -
FIG. 2A —Description of Elastomeric Finger Grip - The
elastomeric finger grip 6 would have a throughbore 20 whose internal diameter would be less than the diameter of stick pens currently available.Finger grip 6 would abut the main barrel and be attached by means of inserting the projectingbushing 10 into the throughbore 20 of the finger grip. It could be permanently affixed with a suitable adhesive. This is the preferred embodiment although there are various methods of mating the finger grip component to the primary barrel. - Description—Other methods of
mating finger grip 6 to primary barrel 2: -
- 1. A bushing could be permanently affixed with adhesive into the through
bore 20 of thefinger grip 6 and could be bayonet mounted, screw thread mounted, or friction fitted into the main body of the primary barrel whose internal diameter would be configured to accept either a bayonet or screw thread or friction fit arrangement. - 2. The
elastomeric finger grip 6 could be co-injection molded and permanently affixed directly to the projectingbushing 10 on the lower end of therigid barrel 6.
- 1. A bushing could be permanently affixed with adhesive into the through
- Operation
- The user of the present invention would grasp the
primary barrel 2 with one hand and with the other hand insert the ball point end of adisposable stick pen 16 into the primary barrel. Thestick pen 16 would be inserted into thetop end orifice 8 of theprimary barrel 2 and be pushed through thelongitudinal bore 4 of thebarrel 2 until the ball point of the inserted stick pen protrudes through the bottom ofelastomeric finger grip 6. As thedisposable stick pen 16 passes through theprimary barrel 2 it makes little or no contact with the interior wall of thebarrel 2 because the primary barrel is formed to have an internal diameter slightly greater than the maximum outside diameter of any common stick pen or common pencil presently available. Stick pens have very similar outside diameters and are similar in diameter to common pencils. - As the inserted
stick pen 16 continues its journey through theprimary barrel 2 it eventually reaches theelastomeric finger grip 6. The stick pen will now experience resistance because the internal diameter of thefinger grip 6 is formed to be less than the outside diameter of the common disposable stick pen being inserted. Being an elastomer, the internal walls offinger grip 6 will offer radial pressure against the walls of the stick pen. To reiterate, outside diameters of stick pens are very similar and differ by minute, insignificant dimensions. The elastomer expands to accept the stick pen. The elastomeric material has a high co-efficient of friction and the internal walls offinger grip 6 will grip the inserted stick pen effectively. As the writer bears down with pressure as he or she writes, pinch pressure offered by the writer's fingers further adds to the arresting forces within the elastomeric finger grip. Thus the stick pen has no tendency to slide upwards within the through bore of the security pen despite being open ended at the top of the barrel. - Having open ends and with no moving parts to disassemble and reassemble the Rapid Loading Security Pen offers ease and speed during the reloading process. Its ability to accept any brand of stick pen as the refill offers the user unprecedented convenience.
- During the reloading process of the
primary barrel 2 the user should hold the primary barrel only and avoid touching the elastomeric grip while removing a stick pen. The stick pen will slide out of both the primary barrel and the elastomeric finger grip with little resistance. - Operation of the Secondary Barrel
- Tile
secondary barrel 12 captures aball chain 14 as shown is cross sectionFIG. 3A . Theball chain 14 permits the security pen to be attached to a pen stand, a counter top or some other object that would prevent the removal of the security pen from the service counter or work station. -
FIG. 3A shows apendant 24 is affixed to the end of theball chain 14. The ball chain is inserted into the top end of the throughbore 18 of thesecondary barrel 12. The chain is guided into the through bore until the pendant enters thesecondary barrel 12. The internal diameter of the through bore is tapered; wider at the top and narrowing towards the bottom of secondary barrel 12.The top end of the bore would be large enough to accept the pendant. The bottom end of the bore would taper to a diameter that would only permit the chain to exit the bore. The pendant's travel is eventually arrested by the narrowing through bore and the ball chain is securely but removably affixed inside the secondary barrel. - There are numerous ways to construct my invention as this would be obvious to those skilled in the relevant arts.
-
- 1. A magnetic metal band or plate could be affixed to the primary barrel so that the barrel could be attracted to and held by a magnet for unique mounting and presentation possibilities.
- 2. The
primary barrel 2 could be formed in an eccentric rather than cylindrical shape in order to present a larger, flatter barrel surface that would more readily accept printing of logos and brands for advertising purposes.
- The exemplary embodiment described above has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention, the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
- The reader will see that this improved security pen is superior to prior art in a number of ways.
-
- The rapid and easy insertion of stick pens as the refill obviates the necessity to order specialized refills
- The use of common stick pens as the refill is economical.
- There is a degree of practicality, ease and convenience considering the ubiquitous nature of stick pens
- It provides a rigid barrel with substantial surface area on which to print indicia.
- It provides a tethering mechanism that is easy to repair if need be.
- With no moving parts to disassemble the security pen is fast to reload.
